DUI-ll? ASH-PAN FOR LOCOMGTIV ES.

To all whom it may concern Be 1t known that we, THOMAS F. CAIN,

and WALTER A. SKlNNER, citizens of the United States, residing at Montgomery City and Moberly, respectively, in the counties of Montgomery and Randolph, respectively, and State of Missouri, have invented certain new and useful Improvements in Dump Ash-Pans for Locomotives, of'which the fol- Our invention relates to new and useful improvements in dumplng pans forlocomo tives and the object of our invention is to provide a pan adapted to. be positioned 1mmediately belowthe fire box of the locomo tive in position to receive the ashes and coals shaken or dumped therefrom.

A further ob ect of our inventlon is to provide the pan with a false bottom including a plurality ofswingingly mounted pans Which, in normal position, close the bottom of the pan proper and which maybe operated from the ,cab to dump their contents.

construct the panas to prevent thecontinued burning of coals dumped therein and therefore to prevent the clogging of the pan by the forming of clinkers.

A. further object of our invention is to soposition and mount theswinging pans as to render them readily accessible for cleaning purposes in case they dobecome clogged. And a still further object of our invention is to provide a simple and etfective means for swinging the movable pans to dump their contents.

With these and other objects n 116W, our

invention will be more fully described, illusin all the views of the drawings by the same.

tion includes a body member or pan proper, 10 open at its upper and lower ends and positioned immedlately below the fire box of the locomotive with its upper end spaced a sli 'ht distance below the fire box in order to ermit the free passage of air to the fire, and a pair of swingingly mounted dump pans 11 and 12 so positioned and mounted as to normally form a closure for the lower end The body member lar inshape with its side and end walls converg ng mwardly, as shown. The slde walls are'connected centrally at their lower edges by a transversely extending brace 13 which, when the pan is in position, seats over the rear driving axle of the locomotive and assists in supporting the pan. This brace, as shown, is arcuate in section to conform to the axle and not only serves to brace the body member of the pan, but also as a pan tition wall betweenthe adjacent ends of the dump pans 11 and 12. Each of these dump pans lncludes a semi-cylindrical bodyineznber provided at its upper ends with outwardly directed trunnions 15 which are journaled in suitable ears 14 formed on the lower side portions of the body member 10. As shown, these cars and trunnions are formed at a slight distance from the centers of the ends of the pan, whereby the pans will normally be held by gravity in operative position to close the lower end of the body member, the inner or abutting sides of the pans being held against downward swinging in a manner to be presently described.

The lower edge portion of the sides of the body member are cut-away as at 16 to provide space for the inwardly directed flanges 17 of strips of iron 18 which are seicured by their edges to the outer faces of the side members, these iron strips being so formed that their flanges 1'? extend inwardly to form seats for the reception of the flanges 19 or extended portions of the upper side edges of the dump pans l1 and l2. The opposite ends of the side of the dump pans are provided with strips of angle iron 21 which engage with strips of angle iron 22 carried by the end portions of the sides of the body member, while the outer sides of the dump pans are reinforced by strips 23 which have upwardly and outwardly directed lips 24: which engage against the outer faces of the ends of the body member. T he V v V 1,106,545.1

inner sides of the dump pans bear their outer faces against the arcuate upper face of the brace 13 when the'pans arein normalposition. 7 v e I By pivoting the pans as described, they are normally held in operative'positionby gravity andwhen so held form a practically;

air tight closure for the body member or pan proper. It will therefore be seen that any live coals which drop into the. pan will go out for lack of the necessary air to support combustion and all formation of clinkers f within the pan is therefore" avoided. More over, by mounting the dump pans in the manner descrlbed, when their inner ends are e v swung upwardly to dump their contents, the

. pans are'spaced as far above the road bed as 'gwhen-in normal position and all dangerofripping thepans from place, whil e dumping;

them during movement of the l ocomotive is V avoided.

When the pansare being empt ed they are readily accessible with a bar to clean out suchclinkers as may have formed asltheir widest opening is under the dump grates either in frontof or at the back of the "fire b x.- l w e As a means'for simultaneously tilting the movable pans to dump their contents, We have extended the trunnions upon one side of the pan to receive pulleys 25 and 26 which are grooved to receivea crossed chain 27, the

grooves in the pulleys beingsuch as to grip It will therefore be seen that rotation of either pulley will cause an equal and opposite rota- 1 tionof-the other. The pulley 26 is provided with a second groove 28 and a crossed chain 29 engages in this groove and inthegrooye of an idle pulleyBO mountedfor rotation upon the frame of the cab. The shaker bar 31; is provided with a hooked terminal 32 V which may beengaged in one of the links shaken or'dumped into the dump pan where they may remain until a convenlentplace for of the chain 29, whereby the chain may be actuated torotate the pulley. 26 and consequently the pulley 25. e In operation, the ashes *and coals. are

It will of course be understood thatboth the body member of the pan proper and'the movable pans will be formed of any suitable metal and of suflicient weight to Withstand the strains amen to whibli neg. .vn be subjected.
